You mean the ones on
https://webapp.geod.nrcan.gc.ca/geod/data-donnees/transformations.php ?
Well, I think the Open Government Licence - Canada should be good enough given 
it is endorsed by https://opendefinition.org/licenses/

Ah ok, now after reading
https://en.wikipedia.org/wiki/Provinces_and_territories_of_Canada explains the 
difference between a province and territory, I better understand your issue 
with the Yukkon *territory*, to be opposed to the transformations available 
for the *provinces*

Well, yes if there is no data published, we can't do much :-) Your local 
contacts within the related agencies are certainly the best approach.

I can't log on that ftp server. It times out.
How are those datasets different from the ones on
https://webapp.geod.nrcan.gc.ca/geod/data-donnees/transformations.php , like 
the BC_93_05.GSB ?
